My editor now open up with the cursor flashing in the middle, it also defaults back to this posistion rather than the left as all text editors should.

This causes the obvious problems of having to left align everything every time. Something is pre centering everything. I install tinymce just to see what that would do, it works fine.

Once when i pasted some text in in pasted in as a very thin colum in the middle, like an invisible table had been made.

In all these instances there is no code in the html view, also i have tried reinstalling the admin and editor. this changes nothing. I am running joomla 1.5.8 on a php 5 and mysql 5 linux server. The editor has been running fine for about 2 weeks that i have noticed.

The is due to a setting in your template css file -

For a quick fix I changed the template back the default one.
