To be honest, with 2.25 I encounter a lot of situations that haven't been there before.

Instance just closing, partly reproducable, e.g. run simulation 1, open result chart, run simulation 2 and move zoom in and out the result while simulation 2 is drawing / updating the previous result.

Memory fragmented or similar message soemtimes shows up, it can be due to my s**** computer, so I can't really tell.
