Strange Images behavior

Hello Julian,
We have a strange Images behavior after updating to WPTools6.
It looks like that embedded Images are painted only when document is focused or something like that.
E.g: User is going throw the list of rtf documents. The content of current document is displaying in your control.
When user is switching to rtf, containing embedded image, in the space, where image has to be, the part of previous document is visible (this part of screen is not repainted). When user clicks on this part of screen, image appears.
What could be a problem?

Thanks,
Konstantin

Hello Julian,
I have made further investigations and have found that such situation with images is happening when WPAppServerMode = true.
When WPAppServerMode = true the space where image is located is not repainted.
Could you pls check what it could be.
Thanks in advanced.

Hi,

the WPAppServerMode has some disadvantages - do you really need it?

Its intention is to reduce network traffic to the cost of some flickering.
