Hi!
To speed up my application I set
AjaxLoad := true
AjaxLoadAlways := true
for all tabs. The speed is greatly increased, but some heavy tabs become to render incomplete when I click on the tab header:
After pressing Ctrl-F5, the form is rendered right:
Those forms are rendered ok if AjaxLoad = false.
It seems that the problem is happened due to the timeout or something like this. The tab just don't have a time to render before it is shown.
