Hi, I agree that there have been several unrelated "issues" brought up here. Some of them are definitely reproducible, if not necessarily easy to capture as an isolated bug report. The "out of memory" problem that Paul Fons mentioned is definitely due to ifeffit's limited, and fixed memory. This can be changed changed at compile time, but is (sadly) unavoidable in the current implementation. Someday there will be an Ifeffit 2 that eliminates this problem. The problem with 'clicking on the file/group area' in Athena on Windows is a long-standing issue. It's fairly common (for me, anyway) to get an Athena session in this state, in which clicking on an existing group does not highlight it or make it current, and moving the mouse over it does not change the font. Sometimes a group can still be chosen as a member of a set. I don't know of an foolproof way to get to this state, but it seems to be more common when reading in several data sets, and after a project has been open and used for a while. This is definitely an irritation and it's been like this for awhile. The rest of athena still runs fine. The easiest and most reliable workaround (that I know of) is to click into a real widget in the Main Panel (so that it actually responds) and then go back to the group list and click on another group. I haven't experienced very many random crashes of Athena. --Matt
