I've discovered that the most recent version of SMath closes when I try to use the paste feature. I do not have this problem in older versions. I have narrowed it down to these versions:

Version Build Date Crashes
0.96 4868 05/01/13 No
0.96 4909 06/10/13 No
0.96 5146 02/02/14 Yes
0.96 5151 02/07/14 Yes
0.97 5154 02/10/14 Yes

Also, I am using Linux Mint with this version of Mono:

Mono JIT compiler version 2.4.4 (Debian 2.4.4~svn151842-1ubuntu4.1)
Copyright (C) 2002-2010 Novell, Inc and Contributors. www.mono-project.com

I hope my description is clear here. Let me know if you need help understanding what I am trying to share. Thanks.

Unfortunately yes. That is where I first discovered the problem. Sorry I did not list that release in my table above. I was just trying to find the latest release that does not have the problem.

Okay, I've found another issue. When I am at the end of a text block and press Shift+RightArrow the application closes unexpectedly.

I've found another, probably related, problem. I have upgraded to Ubuntu 12.04 and now the program crashed when I use either copy or cut. Any progress on this bug? Any more details you would like me to share?

I would like to confirm this bug.

Steps to reproduce: open new file, write random expression, copy it and try to paste (ctrl+c followed by ctrl+v). Results in crash.

I am using:
dev-lang/mono-3.2.8
smath 0.97 build 5154
on funtoo linux

Here is crash message:

Smath now displays file save dialogue like before closing.
