Stupid question, but all of a sudden after years of using VSD

Every time i open a project , or another page in my project it is collapsed (compressed) as a narrow vertical page and i have to drag it out full page

its driving me a bit bonkers, especially as i have been editing 45 pages in one site

Can't find a setting, or a reason, any suggestions anyone

Haven't had that one, but have had problems with page size changing. Fix was simply to re-install VSD. Might help your problem, might not...good luck.

Try this.
Start a new site.
Resize the window and save site.
Close VSD
Open an old site and see if it still does it.
Otherwise reinstall as Gunsmoke suggested.

Tried both still the same

Dam silly problem, got me head scratching
