Since KB5001337 was applied to Windows 10 version 1909, the vertical scrollbar in our VB6 application now shows as a white box instead and no events are actioned from the vertical scrollbar meaning that scrolling is now disabled on all screens that use this control.
Later versions of windows 10 have not had this update and they are all working ok.
If the update is removed then the functionality starts working again.
Is there anything our customers on this version of Windows can do apart from updating to a later version of windows.
They are all on the enterprise version of windows so will still be in service for this version of windows for the foreseeable future and they did not have any plans to immediately update their version of windows and they have a vast estate to maintain so it will give them a problem to either keep the update rolled back or to upgrade to a new version of windows.
