ah! right. you could get even faster redraws on a mp system when another idle processor is available. it might not just wait for the hz timer tick but schedule the woken up mouseproc as soon as it appears in its run queue no? in the text scroll case, you'r already drawing to the screen at a high rate. why should we draw the cursor at a lower rate other than getting a more regular flicker pattern? -- cinap
