I just installed PortableApps.com on my HP 2133 netbook (win xp home sp3) and when I configure Large Fonts, the apps list uses the same line space as regular fonts, so all text is cut in half.
I'll see if I find a way to attach a screen capture of this.
Using PortableApps.com_Suite_Setup_1.5.2_en.exe

Try the 1.6 Pre-Release to see if it fixes your issue:
