I am on BES as well and neither quickpull or the reset feature of quicklaunch will work. I was able to get the quicklaunch reset to work with a work around. When I attempt to change the interactions setting from custom to allow for any app or program, it is greyed out. I believe it is based on the fact that our BES admin has a password policy in place which controls the security timer reset and I do not think that an upgrade to the software will help.
I hope I am wrong but from what I have read elsewhere, I believe this to be the case. On a positive note, the new OS has been much more stable when it comes to memory management. If I only have to hard boot every couple of weeks, I can live with pulling the battery.
