The very first piece of info you should have given: what revision are you using?
I am starting from 1.0 RC2 (codeblocks-1.0rc2_mingw.exe) and then upgrade each SVN build from
http://paginas.terra.com.br/informatica/mauricio/codeblocks/ <--- the compile toolbar is overlapped with debug toolbar in first several builds. After that, when the time pass, new build has been generated, the compile toolbar became this situation. (only 'Build' word displayed) Finally there is a Nightly build.
I try this, however, the problem is still there.
The OS which I test on
1. windows 2000 sp4 (with Chinese character)
2. windows XP sp2 (with Chinese character)
Seems nobody encounter this problem. Shall I submit this on bug tracker for tracking?
