Thanks Mark, but this problem is strictly a design-time glitch. At run time I already have my forms and all their contained objects resized via code, and the glitch doesn't effect their size at that time.

Regarding your last sentence, are you saying that I'll just need to live with this, and if so why should I? Especially when this wasn't a problem in the prior VFP releases.

>I have not worked much with pageframes in VFP9, but the RUNTIME work around would be to put THIS.Height = nn in the INIT of the pageframe. You will need to adjust the height when designing.

>>In VFP 9 I have been experiencing a glitch whereby the pageframe in a form becomes progressively taller in height each time I reopen the form in the IDE. This appears to only occur with pageframes that have many pages where two or more rows are required to display the pages in design mode. Each time I reopen the form, the pageframe become taller than it was the time before, by about 40-50 pixels. This is quite annoying in that the pageframe will eventually become taller than the form height and extend below the bottom of the form. This glitch did not exist in VFP 8 or any prior version.
