I have a strange intermittent problem that almost certainly is nothing to do with Meremortals Framework. Every so often I cannot use the "OPEN" button, I notice that this also applies to the "Based on" button while subclassing. I have to exit Foxpro and re start. The program works fine for quite some time then fails again. I have tried re installing Visual Foxpro, also re installing on a different drive in the same computer. Maybe my system settings are a problem or my hard ware. I am using Windows 95 4.0.1111a and VFP6.0 sp4 on a Pentium 133mhz. Has any one come across this problem?
