Frames within SSTab become invisble after changing resolution

I have placed an SSTab on a form displayed modally
the deisgn was at 800x600 resolution.
I have used the knowledgebase code for making my app immune to resolution changes
The code works fine for all the forms except the one with the sstab on it.
The sstab has a few frames on it and a few std controls .

When i run my app in the resolution it was designed it it works fine but when i run it in another resolution the frames on the tabs,and the controls on it are not displayed

Any help would be appreciated
