Where to change internal browser??!

Hello,

i'm using IDEA 3.0.4 build 701 on a german windows 2k.

When i try to open external javadoc i could see that idea tries to open the page with Internet Explorer at

C:\Program Files\Internet Explorer\IExplorer.exe

but my IE is located at

c:\programme\Internet Explorer\IExplorer.exe

Can i change this? May it be possible to use opera etc. as default browser?

Thanks in advance, Leif
