Why does display only refresh when mouse moves?
Posted on 2008-11-04
I am running a program written in Delphi 6 that takes in real time data through a USB/serial connection.
The program runs OK on other XP machines, but on the EEE PC 1000H the plots (chart components) and data displays (memo components) only refresh when the mouse or pad is moved.
This is true for compiled code as well as development code
I have tried to force refresh in the code, but that does not work and, in any event, the fact that the code runs OK on other machines suggests a hardware glitch.
In the past I would have suspected IRQ conflicts - for info, the elantech smartpad is IRQ 12, the USB ports are 16, 18, 19 & 23 - I have tried disabling the smartpad, but the problem still exists.
Any help appreciated.
