Poor data scrolling, GUI issues !
I am relatively new to RabidMiner nevertheless I have successfully installed rapidminer-5.1.006x64.exe on my Windows 7 x64 (8 GB RAM) and found terrible scrolling performance even with small results as less than 1000 rows in data view. Interesting - dragging scroll view sliders is much more efficient while actually clicking the slider with a mouse and drag the cursor out of the RapidMiner window while keeping the mouse button constantly clicked!
Anyway - I do not cope while scrolling result view of a simple table having ~800 rows and ~10 columns with plain numeric data is consuming more than 1GB of memory by the javaw.exe process??? Please notice - this memory is never released even in case a completely new experiment is opened and performed. In my humble opinion there is some issue with memory management as I was easily able to clog the system previewing a few table of the similar size as previously mentioned what resulted in GUI issues like annoying interactivity lagging, turning toolbar buttons into white "blanks", etc.
