diecastblue,
I had similar problem..I did the following to resolve the problem
1)downloaded updated pandora.jar from http://comicnut.speedxs.nl/pandora.jar
2)created 9 empty files plugtmp-1 --> plugtmp-9 in c:temp (this is my temp folder.)
3)Restarted the PC.
I couldn't get it to work without restarting the PC...not sure why that was required but now...its working great! andora is now creating files in the format plugtmp-10-1, plugtmp-10-2 etc... in c:temp instead of plugtmp-1, plugtmp-2.
