Will Lap Timer work with MS Windows ME?
Yes, Lap Timer 2000 is designed to run on MS Windows Millennium Edition systems as well as Windows 95/98 systems.

Is Lap Timer year 2000 compliant?
Yes, Lap Timer 2000 is fully Y2K compliant.

The cable I built doesn’t work?
Not all printer I/O ports are fully IBM PC compatible. If your lap counting sensors are working for some lanes, but not others then this most likely means that your printer port is not compatible with the full IBM PC spec. You may find that installing a third-party I/O card solves the problem. Most after-market I/O cards implement the full IBM PC printer specification. Use the Edit | Test I/O Ports menu command or Alt+O shortcut to open the port testing window. This window can be used to test the individual lanes sensors.

Lap Timer locks up my computer when I run it?
Lap Timer 2000 uses a high speed timer interrupt to poll your computers I/O ports. Older computers may not be able to handle the high speed interrupts required to sample the ports at 1/1000 of a second. Try reducing the timer resolution to 10 ms. A 10 millisecond timer interrupt will sample the ports once each 1/100 of a second, this should be sufficient for even the oldest i486 machines. If you inadvertently changed the port selection or the timer interrupt period and Lap Timer 2000 no longer runs properly use the /reset command line switch to restore the default port and timing settings.

Lap Timer records multiple laps!
Some cars, especially Formula 1 cars, may generate multiple lap counts when they pass over the lap counter. Use the Debounce Delay setting to increase the quite time after an initial lap triggering event. Formula 1 cars often trigger a lap when the front wing passes over the photo-cell and then a second lap when the rear wing crosses over it too. Multiple laps may also be recorded if the lap counter itself is located at a slow speed portion of the raceway.

How do I resize the main window?
Use the Edit | Settings menu command or Alt+S to open the Lap Timer 2000 Settings property sheet. You can select screen resolutions of; 640x480, 800x600, 1024x768, 1152x864 or 1280x1024 from the screen resolution drop list provide on this property sheet.

What does inverted switching logic mean?
Lap Timer 2000 can be used with lap sensor switches that are either normally open or normally closed. The default is a normally open switch that closes momentarily when a car passes over the lap counter. If you use a switch that is normally closed and only opens when a car passes then you will need to invert the switch logic. Photo-cells are an example of a switch that is normally closed, and will need to use inverted switching logic.

Lap Timer windows and dialog boxes move!
Some versions of MS Windows incorrectly report desktop window locations. If the main Lap Timer window location changes position each time it is launched, or the various tabs on the Lap Timer Options property sheets cause the window to move during use turn off the Retain Windows Sizes and Locations option setting.

Send E-Mail to Author produces a MAPI error!
To use this command your Internet eMail client must be configured as the default simple MAPI client. In Microsoft Outlook and Outlook Express check the options:
    [x] Make Outlook Express my default e-mail program
    [x] Make Outlook Express my default Simple MAPI client

To configure these settings use the MS Outlook Express Tools | Options menu command and then select the General tab.
If you use a different email client check the documentation that accompanied the program for more information regarding simple MAPI client settings.

Lap Timer Options Do Not Work!
This problem is related to the Common Controls Library module installed on your system. If selecting the File | Options menu item does not open and display the Lap Timer Options property sheet please visit my web site, and then go to the MS Windows Essentials page, from there you can download Microsoft's latest Common Control Library Update module. This module includes an automated setup facility and will fix several minor bugs associated with earlier releases of the Common Controls Library including Y2K updates.
