After installation of Lazarus 1.6RC2 and installation of anchordockingdsgn I´ve got the following error message:
TWinControl.WMSize loop detected, the widgetset does not like the LCL bounds or sends unneeded wmsize messages: TScrollBox
BoundsRealized=l=0,t=0,r=1887,b=102
NewBoundsRealized=l=0,t=0,r=1887,b=102
Clicking on ok-button of the message, Lazarus closed.
On restaring Lazarus again, same message pops up directly. Probably Lazarus has started, but IDE doesn´t show up?
I`m running Windows10 64bit on a notebook with a HD-resolution screen of 1920x1080 pixel.
On Lazarus 1.4.4 I had no problems.
regards msc
