Hi Alex!
I don't know what I'm doing wrong, but now the autosize is working correctly.
But I find a little problem:
I put a statusbar in a form and add by the builder 3 panels.
1st panel -> autosize = spring
2nd panel -> autosize = contents
3rd panel -> autosize = contents
When I run this form, in VFP 7 the 3rd panel appears correctly.
But in VFP 9, the sizing grip hide part of this panel...

Please, can you compile the builder in VFP 8 and 9 and post to download?
