Build 266 lag when using Alt A AccelKey for DCPUSHBUTTON

[rsmarks]

After recompiling with Build 266, there is a significant lag when Alt A (or other Alt letters) are used as an ACCELKEY for a DCPUSHBUTTON. There is no lag if I use Alt PGDN or F2 as the ACCELKEY or if I click on the button directly.

Can you give me a sample program?

I created a test program and I see no lag at all.
