Is there any way to open > 1 IntelliJ instance at a time?
I have 4 different codebases here, each with 3000+ classes. Because I need to work in all 4 frequently, I've started opening up 4 projects at once in IntelliJ. This allows me to quickly switch between them, because otherwise I have to wait forever for IntelliJ to parse, cache, etc...
The problem is that IntelliJ often becomes extremely slow and hangs. It frequently will get so bad that I have to kill IntelliJ. But, since it's all one Windows instance, it kills all 4 projects.
Then I have to go through opening up all 4 projects again - taking > 30 minutes to accomplish. The cycle is very painful.
Can I run multiple IntelliJ processes so that killing one won't bring down all 4 ?
I have a dual-process 3.2GHz with 2GB of ram.
