Before posting, have a look at our Troubleshooting page, in case that solves your problem. You may also want to do a search for a bug, before reporting it.
When posting, make sure that you provide as much information as possible, so that the problem can be identified quickly, and solved swiftly: - Your computer specs (OS, gaphics card (-> up to date drivers?), etc..) - Which version of the software you are using - How many images, what file format - When does the crash/problem occur exactly? - Can you recreate the problem? If yes, what is your precise workflow? - Is the same using a different project? If not, what's the difference between the two? - Screenshots, we love those - If you want to post crash dumps, event logs, please post them between [code] LOG HERE [ /code] tags to avoid stretching the page. - etc..
Once the issue is solved, check the solved button on the top right corner of the post that provided you with the solution.
Make sure you post one topic per issue, so that they can be dealt with separately.
