A few users have reported problems in all their Java UI apps on Windows
where the height ot text fields, labels etc looks double-height, with lots
of space below the text.
This always occurs on a system on which there is some Adobe authoring software
installed. At least one of Adobe Framemaker, or Adobe Acrobat Professional (the
authoring software, not the reader) is installed.
The problem is that this Adobe software may be configured in such a way
that it removes the standard Windows "Symbol" TrueType Font and replaces it with an
Adobe Type1 font.
Looking in c:\windows\fonts you should see symbol.ttf. That's a correct windows install.
If instead you don't see that but see symbol.pfm or symbol.pfb, then this
indicates this is the problem.

This is occuring with JDK 1.5 but not JDK 1.4.X
