Dreamweaver problem

[goldengob]

Can anyone please help with this ongoing Dreamweaver problem that I seem to have. I have a 2 inch thick book on the program, but just cannot find the answer to this problem.
I layout my site/s using layout tables, and everything looks just fine. I check my site in the browser view, F12, and everything looks fine. I might then add an image somewhere and everything looks fine, but the next time I go to browser view the alignment just seems to have gone way out of wack.
I then go back to design view to try straighten things out and finish up making it look even worse. Is there any way of locking the tables so that nothing can move and screw up the alignment.
Am I missing something?

Thanks

Are you using % or pixels for the width of the tables?

[goldengob]

Good question. Whatever the default is on the program, I haven't changed any settings.

The default is properly using %, changing it to pixels might fix the problem.

Thanks, I will try that and see how it goes.

Try double-checking the underlying code - we used to run into trouble using Dreamweaver with our old-style nested table layout. I'd insert something, expecting it to be inside the <td> tags, but the cursor would end up outside the intended <td> - things would jump all over the place.
