Same Problem As Everyone Else
I am using DW CS5 and CSS 3. Somewhere along the line as I am customizing my CSS settings, the dialog box turns white with only the thumbnail image showing. It will let me preview in a browser, but will not allow me to continue selecting anything nor allowing me to save or finish. This has been really frustrating since I have restarted every project several times and have lost more than 3 hours of production time so far.
I am running Windows 7 Ultimate with all of the latest updates. I have this running on a desktop with 4 GB of RAM and on a laptop with 6 GB of RAM. It hangs up on both machines. I have also noticed that right before it crashes, it will start acting sluggish as I click on various tabs such as h1, h2, h3 and then back to text or one of the other selections.
I launch Dreamweaver CS5. Then, I select New CSS Sculptor Page... From the Eric Meyer's CSS Sculptor dialog box, I choose my design type. Usually a 2-Column, Left Sidebar layout. Then I choose Cabo Sunset. From there I click on the Customize CSS. I do not check the Select to embed the CSS in the page header. Then, as I go through the process of selecting my parameters on each tab, it starts getting sluggish and finally, without warning, the dialog box goes blank except for the thumbnail in the lower center section of the box. At this point, I cannot salvage it no matter what I try. I have even tried keyboard shortcuts to try to make it come around. I have deleted teh dat file and have rebooted my systems and have launched DW clean with no other apps running in the background just to make sure something else wasn't causing this to happen.
