I used to have 7 pages, and everything worked fine. Now, on most computers, everything still works fine, but on some computers, activating some of the pages causes an 'insufficient memory' error or directly causes the Windows' 'this program has performed an illegal operation' or the memory could not be 'written' error.

This indicated there is no special line of code where the program stops, it just somewhere/sometime (but always before finishing the Activate-code) seems to notice that something is wrong.

I have seen the memory error occur on my page frames when I accidentally caused a recursive loop in the refresh events. I had a page frame with several pages and a refresh method of a button on the page frame called the refresh method of the page. This caused a rather nasty loop unil the program errored out. You might want to use the debugger to trace your code and see what is firing before you get the error.
