Hi Folks, I've only recently upgraded to 5.13 and also a new Video card and have noticed on Boot up that the '1' in 'RISC OS 512' shimmers as though there is something going on in that bit of screen memory. It doesn't seem to affect the performance of the machine. I never noticed this before 5.13 but it may have happened. Also occasionally on boot up I get the bottom few pixels of each line of writing displaced up the screen. I also occasionally get a 'lock up' when I try and shut the machine down. If I close down all the active applications then it does not lock up. I'm investigating which application may be causing the problem by selectively closing down of applications. Just thought folks may like to know? -- Barry A. --- To alter your preferences or leave the group, visit //www.freelists.org/list/iyonix-support Other info via //www.freelists.org/webpage/iyonix-support
