I never use DW to FTP large media files. I always use FileZilla for this. It shows me everything I need.
I very much like tabbed viewing; wouldn't work any other way. But to answer your question, DW does not remember window size. You're not the first person to mention this.
Feel free to submit a feature request below.
Thank you Nancy.
No point in our debating the pros and cons of tabbed viewing as it's probably just down to familiarity anway.
But in my case it may also have a lot to do with having always used Macs since 1993 - and I'm guessing you've always used Windows.
Dreamweaver offers the choice of document windows instead of tabs, but then proceeds to negate that choice by insisting on filling the entire screen !
I'll follow your suggestion and submit a request.
