For some reasons, for some of the apps I thinapp'd, when they are run on systems other than the (clean) system used to create them, there are .db files (such as thumbcache_96.db, thumbcache_256.db) created under %Local AppData%/Microsoft/Windows/Explorer in my Thinstall directory, all of which can be near 500MB each!
Long ago, I had created simliar app with Thinstall (the predecessor of ThinApp) and this problem never comes up!
What has changed? What can I do prevent this from happening? All the Thinstall directories of the ThinApps .exe I now created are nearly 1GB big each!
