[SOLVED]Tomcat freezes during Workflows

Hi there, I just observe a phenomenon, I could not figure out yet. I am currently developing a rather complex workflow. When things go less than perfect, the Webpage seems to freeze.

No, I am not reading anything from console (that I know of). I do not use java or javascript at all, currently, except for logger.log ().

and the ctrl-s should not be happening, since I am using the browser and then at some point, the workflow freezes, e.g. when I forget to assign an actor to a swimlane and the transiton sends me into that pit.

Another example,
importing my model failed because I had <default>grün</default> in there instead of grün. After that, I had to press CTRL-C multiple times until tomcat started to shut down. I guess that is the same situation, except nothing is running anyway

And another one : )

* Clean alfresco (no deployed models, workflows etc, done by jpotts "build.xml clean-tomcat")
* upload model to datadictionary/models & activate
* error message tells me something is wrong
* system wont react anymore
* switching to tomcat console, the system hangs here

(I am not positiv, might be a line earlier, sounds logical)

(translation by a more stable mind : MRogers, you are right - its the scroll wheel on my mouse, scrolling the tomcat console window and suspending console output (and tomcat) with that )
