EVENT_VSCROLL not working with Page Up

[holly7787]

Hello everyone, i'm using LabWindows CVI2012 and i've noticed this bug.

i'm using a table and when I scroll with mouse the event EVENT_VSCROLL is called, also when i click the arrow up and down, and when i press Page Down button on keyboard.

when i use Page Up it seem not working, or not every time.

have anyone noticed it?

thank you
