Hi, i've seen the same problem here, so it should be reproducible.
I think, the issue is related to some error in the focus control. Steps to reproduce: 1) Select "File -> Save as" from the menu. 2) Notice that the first folder in the pop-up dialog is marked 3) Press the save button 4) The pop-up dialog is now in this first folder. 5) The process can be repeated. Basically, the dialog is confusing in that pressing the "save" button actually triggers a double-click on the selected folder in the dialog. Workaround: The trick is to get rid of the focus on the folder. At the bottom of the dialog are two fields (filename, format). As soon, as one makes a selection here, the focus in folder dialog is removed and the "save" happens as to be expected. Additional information: 1) The folder list appears to lag the parent directory ("..") for navigation. 2) I've seen this problem on a different version: 1.7.0.4-3, but it appears to be the same from the description, so i post it here. Hope it helps Lars Dölle
