I am using DTPro and am having some weird issues with views.
I tend to use either Split or Three-Pane views, both in Widescreen. However, every once in a while, the preview pane of those views just stops previewing. I have not been able to figure out why or when, but I have to close DT and reopen for it to start again. It just seems odd.
I am using a new MBP running OSX 10.9.1.
