sorry I have a few things again
1. if you set the covalent radius to a very high level (e.g. > 2 for Hydrogen) so that these atoms have lots of bonds, molecoolqt crashes.
2. Strange beahvior: Open a structure, disable the unit cell. Open another structure and at the moment the file dialog opens, the unit cell gets activated again. When you open another structure, the unit cell is deactivated again.
3. Is it possible not to show hydrogen bonds with hydrogens activated?
4. Calculation of a not existing isosurface takes 100% cpu time.
