Scratch

I have several problems with Scratch 1.3:

1. Thumbnails of some gif files in my folders are not shown (and the corresponding files cannot be imported)
2. Often the dialog windows do not show up completely
3. Lists are extremely slow. Creating a list of 900 elements in a repeat block takes 54 secs!
4. often when I save a file with a new name the new name doesn't show up in the title bar (but the filename is correct as if I try to save it again with the new name Scratch says that a file with that filename already exists)
5. once, after saving, all "details" (variable names, fixed values) contained in blocks in the script area disappeared (for all sprites). I had to close and reopen the file to have everything back.

and...

1.3 is a lot slower than 1.2.1! But I need lists in an official release...
