I ditched the 'for U3' version of PFF (and PTB) in favor of 'plain old' PFF and PTB...and I'm happy with the results.
Is there a way to make these apps appear on the U3 launchpad? For example, would adding this line to the XML file do the trick?
[illegal symbol]APPLICATION guid="FirefoxPortable" launchOnStart="N" lastUsed="2/27/2006 11:01:21">\Firefox_Portable_188.8.131.52_en-us.exe[illegal symbol]/APPLICATION
(Where "illegal symbol" refers to the sideways "v" that is not allowed in these forums.)
Thanks for your help.
