Today I have performend an update from MindManger 7 to 14 and now encounter the issue that the tool is terribly slow with some maps (small ones). Opening those maps results in the inability to select branches and clicking a button in the menu band took forever. Some of the maps are really small (<200kb) and do not contain any map parts or something like that. I have tested the maps on two different computers (1. Windows 7 Professional x64, i7 2600K, 32GB RAM, 250GB SSD (150GB free) 2. Windows 8 Pro x64, i5 3320, 8GB RAM, 250GB SSD (130GB free). All maps where working perfectly with MindManager 7, so no problem in general. I am running MindManger 14.2.321 German. Do you have any idea how to get rid of this issue?
