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
