Hi Casey,
you can use the "Doevents" instruction.
This tell to VB to process the event in the FIFO queue of Windows.
You can place a "doevents" instruction where you think is better.
I suggest to don't perform a doevents as quick as possible but 
use it very rarely inside your loop. 

I worked a lot with "seismowin" to these problems.
