Subject: Re: MouseMode = mmSelect/ mmQuickSelect doesn't work
In reply to: Niek Bakker 's message, "Re: MouseMode = mmSelect/ mmQuickSelect doesn't work" on 03:14:10 02/15/01 Thu

Hi Niek,

I'm sorry about answering too quickly on this. I have double checked, and the rubber band mouse handler does not work when the TImageScrollBox has the Centered property to True. I omitted to document this. In .LoadImage if you remove the Centered := True line, the rubberbanding functions properly.

Best regards,
