--- Comment #1 from rickcockrum@gmail.com 2010-02-03 14:38:38 --- Using stock Wine 1.1.37 on Ubuntu 9.10.
I have several dialogs which have an up-down control with a static control as a buddy. The up-down control has the UDS_ARROWKEYS style, acceleration increment set to 25, and delay time set to 0. Under Windows, using the mouse and the arrow keys both change the position of the up-down control by 25. Under Wine, using the mouse changes the position of the up-down control by 25, but using the arrow keys only changes it by 1.
