XGrabPointer, using owner == True, returns BadValue errors when an event_mask is given. The function acts as expected (sending events given in the event_mask to the specified window) even though it returns this error. This error was not returned in R3; behavior between the two versions (aside from the error return) is identical. Is this a bug, or am I doing something wrong? Email responses would be appreciated. jim frost saber software jimf@saber.com

I am posting this not as a reply but having noticed similar
behaviour in controlloing the sash in the VPane widget of
HP widget set. I posted an article regarding that before
(Haven't seen any responses yet). If somebody does respond
please put it on the net also so that others can benefit
from it also.
Thanx

The Xlib manual says the event mask must be "the bitwise inclusive OR of the valid pointer event mask bits". Valid events are listed under "POINTEREVENT" on p. 349 of Scheifler's DP book. Your event mask probably contains invalid events. R3 sample servers incorrectly ignored invalid events. R4 sample servers correctly give you a bad value error.
