Visual Studio 2005 Service Pack

[TTn]

I'm having a slight issue with SP1 for 2003.

First,(saved as file to disk) it took forever to prepare, and install. Each window took several minutes to finish. I assumed that this was because of the large file size.
This may be okay.

Then I rebuilt a project solution, so it was side by side in another folder, separate from the old project build.
The new project build throws the JUST IN TIME COMPILER error for a simple PictureBox.image update, while the old build does not. I've double checked this behaviour between builds.

So now I don't know whick build error is correct, or how it would be fixed in that context. The picture update is trival, so an On error resume next, statement is used, instead of the Try Catch, because the tryCatch causes the JIT exception for no apparent reason. I've seen this problem sometimes in the Microsoft samples for GDI+ManipulateImages, and GDI+Animation.
This seems to be more of a system state problem, which affects things in an unintended way.
