I'm having a problem with a program I am working on. I keep getting seemingly random "Unhandled Memory Exception Excpetion Error" crashes. Whenever they happen in a debug build, BLIde opens timer.bmx and highlights this line:

Function _TimerFired( timer:TTimer )
-->	timer.Fire
End Function

Here is the code I have that deals with timers:

  Field DrawTimer:TTimer, ProgressBarTimer:TTimer

  Method StartDrawTimer()
  	DrawTimer = CreateTimer(120)
  End Method

  Method StopDrawTimer()
  	If (DrawTimer) StopTimer(DrawTimer)
  End Method

  Method StartProgressBarTimer()
    ProgressBarTimer = CreateTimer(10)
  End Method

  Method StopProgressBarTimer()
    If (ProgressBarTimer) StopTimer(ProgressBarTimer)
  End Method

The error does not happen during the execution of any of the above code; instead, it happens after the timer is created (presumably when it fires). I cannot find any common thread with the crashes. They happen at different times when the program is doing different things under a variety of different circumstances.

I noticed this line in the documentation for StopTimer:
Once stopped, a timer can no longer be used.

I did not think that applied to creating a new time using the same variable. Does it?
