[Oberon] linux oberon Display update interruped ?

[Thoken]

With V4: did you try to adapt entry "timeOut"  in Web.Profile ?
In V4 module HTTP I once changed VAR waitForResponse to type LONGINT
cause I suspected occasionally erroneous results by waitForResponse *
Input.TimeUnit.
I can't recall what the exact effects were, when I did this some years
ago, but I still feel rather comfortable doing some web tasks with V4.
Integration with Mouse/Kbd input is indeed minor, input is blocked
here on no server response (happens rather rarely though).

regards
