What steps will reproduce the problem? The below is the version installed by Pencil-1.2.0.win32.installer.exe 1. With an epz open in Pencil. 2. Attempt to start Pencil again 3. Observed result; following message is displayed "xulrunner.exe has encountered a problem and needs to close. We are sorry for the inconvenience." Error Data: AppName: xulrunner.exe AppVer: 1.9.2.3705 ModName: mozcrt19.dll ModVer: 8.0.0.0 Offset: 0001761a Microsoft detailed report attached in case it helps. 4. Desired Result; A new instance of Pencil should open. 5. Alternate Desired result; Enable opening of more than one document at a time or create method to copy objects (and tabs between epz documents.)

A temporary workaround is actually possible. It's possible to open Pencil as a plugin in Firefox and the desktop version at the same time. Copy paste operations are available between the two instances.

you can also clic on file > New Window And drag & drop your file in the new window

Thanks for the suggestions! To address the Alternate desired result in 5 above, I've been using the following workaround: Document > New Window (Window 2) (Alternately) Document > Open... Select Object in Window 1 Edit > Copy Switch to Window 2 Edit > Paste

Issue described in 4 above still occurs and should be addressed.
