5.5.3 studio absolute fresh install in the last 3 weeks on a fresh installation of xp pro sp3
So until yesterday no issues with this - note entry via mouse was fine and no screen rewrite problems whatsoever.
As far as I know, I have not made any changes in preferences or settings or to the system anywhere else that could be traced back to being the cause of this.
So, I switch to note entry mode, drag the cursor into the page (I am using page mode because I prefer it to the edit mode) and everything disappears except for the current duration value and sundry accidentals as I drag through the screen trying to find the right place to click and enter the current note.
I did have this before and decided to roll-back to 5.1.1 which never showed this failure.
Has anyone experienced and developed a solution or do I just rollback as I did before.
