Hi Jon,
I've just spent a few hours building dozens of pages up from scratch with up to a dozen modules per page, mostly Text/HTML. I'm mainly using IE7 and this is DNN 4.51.
There was some hassle with the quick-edit mode:
First, when entering quick-edit mode to edit the module title, the cursor would often not appear until the mouse was moved. Making changes to the text in the title would then also not be visible until the mouse cursor was moved a little. I had noticed this previously, but it really became apparent when I had to edit hundreds of titles. It also seems to happen in the main text area when that is edited inthe same manner. Sometimes it acts like it's not working.. going in and out of the mode or refreshing the page can fix it.
I also have a suggestion for improving the usability of quick-edit mode. On most of my sites there are two problems with the quick-edit icon/s. First, more often then not, they popup nearly on top of each other and at the same time are in the way of the module-menu. This makes it difficult to find the right one to click on.
And second, on pages with lots of text modules, when using the mouse to edit, the icons popup all over the place and hang around being a pain, making for a messy screen... and then it's less easy to find the one that is wanted. It's like you move the mouse over the screen towards a text area and by the time you get there 20 little icons have popped up all over the screen.
In addition, the module's own menu is also often entwined with all these little icons and it makes a right mess. I have to click away from the browser and wait until they have all vanished, before I then carefully line up the target for another run at it.
I believe that the solution to this would be to provide a delayed activation for all of these menus. If it required a short pause with the mouse on a menu before it pops up, then it would not happen at all when the mouse is moved across the screen.
This is how the Windows Start menu works and remains relatively smooth... by having about half a second delay before any submenu opens.
I think it's worth trying out in any case.
