After last night's windows update, I am getting a dialogue box as follows:   Your DWM is incompatible with Aero Glass!   See debug log for details.     Do you want to retry symbols downloading?                        [Retry]  [Cancel]   The title is a black box.   Hitting retry does nothing.   My log contains: [2015-03-12 23:41:15][0x154:0xEBC] dwmcore.dll version 6.3.9600.17674 [2015-03-12 23:42:15][0x154:0xEBC] udwm.dll version 6.3.9600.17284 [2015-03-12 23:44:15][0x154:0xEBC] DWM incompatibility error 0x1E3   I can't get at the update 1.3.1, as the website leads me to a 404 error. Any suggestions?   Thanks Jules
