I had a pageframe class in one of my form. I went into the class designer and change the number of pages from 2 to 1.

So, normally, when I tried to access my form at design time, it didn't want to load because some objects didn't find the pageframe.page2 parent. So, I use myform.scx and delete all the entries on page 2.

I tried to access my form again and it was the same time. I had to pack the scx to be able to access it.

Visual FoxPro is then using all the deleted records as well at design time.
