MC .NET freezes when closing multiple chart windows

I have a workspace with 20 charts and I wanted to close all but to charts.
After closing about 5 -7 charts, MC freezes and has to be forced to close.

Hello hairyMug,

Please download and unzip the MC dumper to your PC:
https://dl.dropboxusercontent.com/u/279 ... Dumper.zip

Do not restart MultiCharts when the error window appears.
Keep MC running and the error window open.
Start the MC_Dumper gui.exe
In MC Dumper window please select the version of MultiCharts you are having problem with in “Product for Dumps selector”.

Please keep in mind that MultiCharts, MultiCharts64, MultiCharts .Net, MultiCharts .Net 64, MultiCharts .Net SE, MultiCharts .Net SE 64 are all different products and the one you are having problem with right now must be selected to collect the required information.

Do not change any other options.
Press Make Dumps.
This utility will create dumps and logs, pack them into a zip file and open the folder containing the file once the procedure is done.

Please send me this file to support@multicharts.com and we will analyze it.
If the file size is >10mb please upload it to any file sharing hosting and send me the download link, otherwise send it via email directly to me and our developers will analyze it.

Create an additional screenshot of the error and send it to me.

after adjusting some of my code, this problem is very infrequent, which leads me to believe that it is all based on my code...
I will re-post if I can reproduce the issue on a consistant basis...
