Try using a name expression instead of macro substitution. Name expressions execute faster, which may make the code run properly inside the timer event. Something like:

if (tmpcurrballloc) = RGB(255,255,255)
etc....

You may also want to increase the interval between events, just to test if the timer can process all the code in the timer interval.

Does the thisform.currballloc property hold a reference to the desired textbox?

Hope this helps.
