GUEST: Open app

GUEST: Starting Netbeans.

GUEST: Not sure wether this is related or not, I tried to stop a netbeans task (I tried to delete a folder from the projects explorer tree but it took too much time si I decided to cancel the deletion). The task could not be stopped and I closed Netbeans. I checked Windows processes and even after several minutes Netbeans was still running and its proc / memory consumption was not moving anymore. I started the program again and a new instance of netbeans appeared in the processes list (I thought this was not possible). I just killed the old instance and the error "NullPointerException at org.netbeans.modules.php.dbgp.breakpoints.LineBreakpoint.isValid" appeared while starting the new instance (small indication in the bottom but everything was working correctly).
There is no link, but there is another tinyl thing that could suppose a small fix : when I rename a file in the project tree and that I press Enter twice to validate the new name and open the file this creates a small bug :)
I hope th
