I have been using a graphing OCX which generally works fine. However on one machine only (out of 4), after leaving the screen that I use it in, there is one screen in my app. which always fails when I try to run it! This second screen is fine as long as I stay away from charting. Error message is:

The program has performed an illegal operation and will be shut down...
VFP caused an exception 10H in module VFP.EXE at 0137:005c8e78... 
 
I have tried a second OCX and get the same error on a machine where the first OCX has never failed!

Any suggestions?
