Tool tips and -accessibilitySetOverrideValue:forAttribute:

Subject: Tool tips and -accessibilitySetOverrideValue:forAttribute:

I call -accessibilitySetOverrideValue:forAttribute: on a button cell to change the value of the AXHelp attribute every time the user presses or lets up the Option key. UI Browser reports that the value of the AXHelp attribute was successfully changed every time, but VoiceOver stops speaking the new value after I change it the first time. Same result if I use the Command key to trigger the value change.

I tried setting the override value to nil first, but it doesn't help.

Any hints about what's going wrong or what I can do?
