Issue I468 [feature,resolved] Improve responsiveness on PA load/save (Asynchronous I/O). Prior to 8.0.5-TEST1, the SIMION GUI would freeze and not respond to events while a large PA was loading or saving (which can be over a minute for large PAs stored on a remote network share), and it was not possible to cancel the load/save other than by terminating the process. Reported by tbraun-20080116 http://www.simion.com/discuss/viewtopic?p=2116 In 8.0.5, SIMION responds to events while PA loading/saving occurs, and the operation can be aborted by pressing the ESC key. Implemented in 8.0.5-TEST1.
