I just got and installed 2.22 pro for windows. I can not get the “insert block” to work at all. I created a block, then did the “undo” two times to get back to the entities as the manual instructed if I wanted the entities back. In an other drawing that I wanted to use the new block, nothing I tried would work at all (I have never even seen “figure 17, block list” on pg 36 of the reference manual). I also tried to "insert block" in the original drawing that I created it in, also no luck. Do I need to delete Qcad and reinstall it or what else can you suggest.
