[protege-discussion] Mac Leopard / Prompt problem was Re: Memory problem?

Hi Karin,

I suggest that you use Protege 3.4 RC 1 or later. We are very close to 
making the Protege 3.4 release, which contains many improvements from 3.3.1.

If you can send me the ontology offline, I can take a look to see what 
causes the problems.

Other people have reported problems when using the Protege default L&F 
on Mac OSX, and it is recommended to use the Mac L&F for this case.
It doesn't really make sense that Prompt has a problem with this.

How did you increase the memory and how do you start Protege? If you use 
the Protege executable, you need to edit the plist. If you run it using 
the, then you need to adjust the script. We have detailed 
information on how to increase the heap size on the wiki [1]. If you 
start with the script, the console will tell you in the first line with 
how much memory Protege is started.
