This is kind of hard to explain, so please bear with me... Whenever I try to move a module or a connection in the Process tab, the module doesn't drag across the screen, or move at all. If I minimize the RapidMiner window and then maximize it again, then the module has moved. Every time I make a change, I have to minimize and maximize the window for the change to actually register on the screen. Also, when I try to switch to the results tab, absolutely nothing happens. When I very first start RapidMiner, or if I restart it, I don't have the problem for the first minute or so, and then it starts up again. I've tried updating RapidMiner, and uninstall/reinstall. I can't find any other posts about this problem, but I also don't really know what to search for. Any help would be greatly appreciated!
