I've noticed the following bug.
When installing an app, it gives you an option to give a custom name to destination folder. I gave "FirefoxPortable" the name of "[INTERNET]FirefoxPortable", and gave the [INTERNET] prefix to all the apps that go under Internet category. I gave other prefixes to other apps to keep them organised and easier to find also when accessing them from a file browser without neeeding to start the PA platform (which takes to long to load all the apps from my USB stick).
Everything works fine, the apps show in the menu, they start and so on... just the "Check For Updates" function refuses to update them!
I guess it is a bug. Anybody willing to inspect?
