And here it is the first application of this feature: I've updated some of the plug-ins in the Extension Manger. Once downloaded you will find ComboBoxList, NumericUpDown etc... grouped in the "Controls" folder; PieChartRegion now is under the "Plot" folder (same can be done for other plugins by each developer)

Hello. I downloaded SMath Studio for Mono (Desktop Linux version) using link in this topic (first post). I also updated mono fololowing instructions on Mono oficial web page for my distribution. Sorry, but the program still doesn't function properly (it just dumps it's core in some cases). Steps to reproduce:
1. Install Mono distribution following instructions on official website (for your distribution).
2. Download SMath Studio for Desktop Linux (by the link from this topic or any older version).
3. Run the program using launcher in SMath distribution (run smathstudio_desktop_mono script).
4. Enter a simple expression like a:=1
5. Select this expression with mouse, press Ctrl+C to copy or choose Copy in context menu.
6. Paste this expression anywhere in the worksheet (Ctrl+V or via menu Paste).
7. Result: A dialog is displayed (Save changes? Yes/No/Cancel), but it doesnt'n matter what button you press. The program crashes.
It generates a traceback. First and last messages in this traceback are:

Could you please fix this? SMath is very useful and this bug is a real "pain in the ass" because I can't copy enything and when I forget about it it crashes without saving the document (like yesterday with a simple calculation for cassette player amp). Also, there is a bug with focus. If you swithc to another window and then back to SMath, the focus (placeholder) is still displayed but really there is no focus that is very annoying when copying something from another program (the number can be inserted without crash, previously described bug applies to expressions).

OS: Ubuntu 12.04 with current updates
Mono: current version (mono-devel, mono-complete) from official webside (for Ubuntu)
SMath: from this topic (Desktop Linux version)

The same behaviour is on Centos 6.7 with older Mono version so I think that the problem is not in mono.

Thanks for attention.

Hello. Thanks for your attention, hope it will be easy to fix this copy bug. I just want to say that I noticed a similar problem in Windows version 0.97 (5890). Program doesn't crash but it often tells that "Paste from the buffer was not successful" (in Russian). It seems that in Linux this bug leads to crash but in Windows only prevents from paste. Expressions to paste itself are "good" and can be pasted if you introduce brackets in target expression.

Some other details that revealed. If you select the expression's "internals" then copying is OK! But if you select it as a REGION then SMath crashes on Paste. So there is a workaround: select internals to copy. It's only convenient when copying one or several expressions but it works

Great work! Thanks, now this copy-paste bug is fixed! Will now also update the Windows version... I create important calculation model for my work in your program now (in Windows version), SMath has changed the world and significantly lowered Mathcad monopoly in paper-like calcs. If it will be able to do massive calculations (like loops) without tweaks fast (not sure it is fixed yet) and if it will provide a Mathcad-like 2D plots (with strict range set with variables and multiple functions with adjustable style) Mathcad will be almost not required for the routine tasks (we have a Mathcad license but I like SMath more).
