I’ve succesfully used MM1.4 and MM2.0gamma (last version 20200324) since many years and never had an issue like this before:
Last Monday I had a session for several hours and had left everything on for a coffee break. I came back and wanted to continue with next sample, and nothing worked. MM2 was totally frozen and I had to quit it from Task Manager (64bit Win10). In itself nothing spectacular BUT that it does not start anymore is. When launching I get the ImageJ main bar and nothing else.
Typical procedure follows: make a back-up copy of the installation on external drive, remove and reinstall the software. No change, still only the IJ bar appears, although that seems to be functional. It says JAVA 1.8.0_152 which is different from the Java on my PC (271).
Really standing on the hose now, anyone ideas?
