I'm using both Fedora 17 and Windows 7 for my software development, and I'm using Eclipse.
One thing that I noticed with the Eclipse in Fedora 17 and in Windows 7 is the workspace. Apparently the element spacing in Fedora is much larger than in Windows 7, resulting in smaller typing area for Eclipse in Fedora than in Windows 7.
I also noticed that the large element spacing happens not only in Eclipse, but also on any Java GUI program that I run on Fedora 17.
Does anybody know how to deal with this kind of issue?
