Error when using ControlGetPosHeight and width in C#

[mattiej]

When I try to do

int height = _autoit.ControlGetPosHeight(title, "", "[CLASS:WindowsForms10.Window.8.app.0.2ea1b40_r13_ad1; INSTANCE:4]")

It sets the error flag to 1 and returns 1

Title is the correct window title, it works for other 

Edit: [CLASS:WindowsForms10.Window.8.app.0.2ea1b40_r13_ad1; INSTANCE:4] is what I get from the window tool.
