Dear friend,
I really do not think that, when we encounter a problem with our tool on a new platform , it's solution is to " STEP BACK " to previous versions of that operating system.
Now, Once, I have a problem with the font system of HDL Designer under Mandrake Linux 9.0, I could solve the problem by simply installing an additional XFree86 related library, place on the thirs CD of mandrake.
I'm wondering if these two problems can be the same. any how, the file, which I mentioned above was near 80 kbytes and it's name contain "XFree" and "compat" I think it is a kind of update needed for compatibility issues.
Since, XFree86 is not related to any of Mandrake or redhat, may be you can have a simple test.
Now, IC5.0 works well under my mandrake 9.1.
