Strange Java bug or error shows beach ball

[DeeAge]

Greetings

 

I run into 'beachball mode' when using Java supported software such as 360Works SuperContainer or MirrorSync.

 

Strange: on same MackBook, using a different Mac OS user account on the same machine, it does not replicate this Java bug or error (so I can work happily on other accounts...)

 

Samples:

1) After opening the MirrorSync configuration panel nicely, it runs into 'beachball mode' after a couple of seconds and I have to force quit out of Java...

 

2) I have the same behaviour with SuperContainer bulk image upload, it runs into 'beachball mode' after uploading 2 or 3 files and I have to force quit out of FileMaker...

 

 

Again: those errors are not happening on the same computer when using using a different Mac OS account.

 

 

MacBook, Mavericks, Java 7:51, FMP13

 

I have removed all Java files a couple of times, and re-installed the latest Java: still the same problem

 

I have re-installed Mavericks to the MacBook, cleaning, repair disk, repair permissions: no change

 

 

 

Any help would be appreciated. Thanks
