I've had issues that I thought were issues but were not really. How's that for a mouthful! Anyhow, I find that, if in EQ5, I save the block/coloring/whatever, I sometimes have to close that project and re-open it in order to find what I've just done. Sometimes very tedious but it's all always there. In fact I thought I lost an entire project a couple of weeks ago but it popped up when I opened the entire file string vs the short name for the project. I re-installed EQ5 on my now almost 10 yr old computer at the time running Windows 7 professional. Other than those little quirks, I really haven't had a problem with it.
