I am having a problem running AC10 (with latest patch 966) on my Dual processor G4 macintosh. The mac is completely up to date concerning software (10.4.7).
The problem I'm having is in the Section Window. Some lines are not selectable, when moving the arrow tool over these lines the cursor does not respond, it's as if the line does not exist. Also when trying to use the arrow tool to select by putting a box around the lines it will select items outside the box.
I did start the project in AC9, saved it in AC10. I saved the file back to AC9 and this problem went away.
Has anyone else had this problem?
