When the main Unitrunker program crashes, it creates a crash dump file. When reporting a crash, you may be asked to provide a crash dump file. Here's how to locate that file.
Look for a file named like so in the %TEMP% folder. The exact location of your %TEMP% folder depends upon your installation of Windows. For example, it might be "C:\TMP", buried under "Documents and Settings" or "Users". No worries, type "%TEMP%" in the location bar of Windows Explorer (not Internet Explorer) to view the folder's contents.
For example, a crash at 3 o'clock sharp on April 1st, 2011 (no foolin') would produce a file named "Uniform.20110401-150000.dmp". If UniScope crashed, the dump file for this program would similarly be named "Uniscope.20110401.150000.dmp"
In some cases, a crash dump can't be generated. The program uses DBGHELP - a Microsoft provided utility - to generate crash dumps. Windows XP and newer include this utility. Crash dump files are normally a megabyte or more. If you find a crash dump file that is tiny (100 bytes), open it in Notepad. It may contain an error message like "Incompatible DBGHELP.DLL". If you're running Windows 2000, you can download DBGHELP.DLL from Microsoft.
Not all crashes are caught and logged. Crash dump file or not, don't by shy. Report these errors so they can be fixed for the benefit of all.
When providing a crash dump, you can compress it as as zip file (a "compressed folder" in Windows XP/Vista/7). You can share the dump file in Google Docs, or email it to the author as an attachment. The author can be contacted via his gmail account. The email address is the name of the program.
