Revision: 143
http://sourceforge.net/p/mwinapi/code/143
Author: ziewer
Date: 2017-12-12 11:38:03 +0000 (Tue, 12 Dec 2017)
Log Message:
-----------
Reverted modification in SystemAccessibleObject.Visible (due to incompatibility with Google Chrome)
- now 'Visible' only check state INVISIBLE (as it was before rev.142)
- new method 'IsState()' can be used to check any state (e.g. OFFSCREEN) e.g. for tabs in Firefox Quantum v.57
- catch NullReferenceException in 'State' (e.g. sometimes caused by IBM Notes)
