Hi René,
We use TFS and seem to have no problems.
My guess is that SVN somehow screws with the binary part of the exported window / object.
When you "edit the source" of you window you won't see it, but when you "export" the window to a file, you will see something like this at the end:
Start of PowerBuilder Binary Data Section : Do NOT Edit
0Ewtest.bin

Why don't you do the following test:
1) create a new simple control with the web browser object
2) export it to 1.srw
3) add to source control
4) check out
5) do changes
6) check in
7) do getlatest on someone else's pc, export to 2.srw and compare the 2 files.
That way at least you will know if it has something to do with SVN.
Are the other users running the same windows version / updates? I'm thinking if there could be different versions of the control on different window versions/updates.
HTH
