>I know what you mean. My grid class has some code that should actually cause an infinite loop, but doesn't. The AfterRowColChange method does a THIS.Refresh, and THIS.Refresh calls AfterRowCall change. I had to have all of these in there to make the grid display like it should, and it BTSOOM why it doesn't crash with an infinite loop. Watching it in the debugger, you can see it go through everything twice, and then it just jumps out.

Erik,

This occurs because VFP does not support reentrancy, it does support recursion. So when your reentrant call occurs VFP sets some kind of internal flag and won't do it anymore.
