>I developed an application a couple of years ago in FPW26. It worked fine till we installed new PCs in our office with MMX and Pentium pro processors. On new systems the application started giving message "Insufficient Memory" where ever a popup list is activated. The dialogue box with options Ignore, Cancel also appear after the error. On pressing ignore, sometime the application starts working but sometimes it hangs. I would be very greatful if someone could help me with this problem.

Try to look at MEMLINIT. One of the settings I'm using are 80,1024,4096.
