Not Enough Memory Errors
I am getting a fair number of these when working in LR4 and exporting photos [1 at a time] while selecting photos by jumping back and forth between Library and Map Module ...

After getting this, all attempts to export will fail; only solution is to exit LR4, which seems to destroy any open instance of IE9.
While exporting, not actively doing anything else on PC.
After LR4 closes, and I close IE9, PC runs really slow for severak minutes, even if all open tasks are closed out.
After PC settles down, can open LR4 and continue exporting photos.
Working on Vista 32 with 2GB RAM; when every slows down, Task Manager shows basically nothing happening with any process.
Is this a know issue; any thoughts or suggestions?
Thanks.
