I have created a map and made a nice lay-out in the printer composer (in QGIS 2.4), the weird thing is, that if I try to save my map as an image or as a pdf immediately after entering the name in the "save as-dialog box" my map disappears from the composer interface, and then it is nowhere to be found. Luckily I did save the template, and only after restarting QGIS can I load the template again.
I don't understand what is going on here and would be very happy if someone can tell me this.
