I post this here because the Project Management Module drives me crazy (when I try to edit the text in PM, the changes cannot be saved).
So this is the issue:
My setup uses more than 30 workspaces (for each instrument, I have a separate workspace), each containing 2 charts of the same symbol with a different time resolution.
Track Time and Price is enabled.
It occasionally occurs that I cannot drag some of the charts along the time axis, after grabbing it. Background dragging and moving the chart with the scrollbar or the mouse wheel works without any problem.
This occurs only for around 5 - 10 workspaces on the right side of the workspace tab area, i.e. the workspaces which have been opened as the last ones during startup.
This behaviour cannot be consistently reproduced, but when it once occurs, even restarting MC does not solve the issue. The affected charts are "frozen", and I have to create new chart windows.
How to reproduce:
Create 30 Workspaces, each containing two charts of the same symbol with different time resolution.
Enable Track Time and Price.
Go to one of the workspace tabs on the right end of the tab area.
Try to grab and drag the charts (no background dragging, this works flawlessly!)
Chart dragging gets deactivated in some special setups [SOLVED]

What kind of computer do you have? (What CPU?)
How much memory?
How much back data do you have on your charts?
Do you have many tick charts?
Any 1 tick charts?
Any other programs running on your computer?

I do not think this behavior is due to limited system resources.
My rig is a X79 board with an i7-3820 Quadcore and 16 GB of RAM. I run MC 64 8.7.7634 on Win 7 64. I have a four monitor setup with MC 64 using three of them. GPU is Nvidia GTX 670 with 2 GB. When the issue occurs, there is no high CPU workload or RAM usage.
I do not use any tick charts. I use continuous futures charts and FX charts of minute data with a data range of not more than 2 years. I do not run any other program in parallel except for TWS.
The strange thing is, I never experienced this behavior in the past, when I had much more chart windows open, even with Tick data.
But I did not use the setup as I use now, i.e. two charts side by side in one workspace with Track Time and Price enabled, so maybe the issue is connected to this?
I'll try to narrow it down.

Re: Chart dragging gets deactivated in some special setups
It is good to know we can rule out system resources as an issue.
There must be something else that cause this behavior.

Re: Chart dragging gets deactivated in some special setups
We are currently analyzing this behavior.
Re: Chart dragging gets deactivated in some special setups
After about a year, any success? I'm having this issue on MC64 8.8 R5.We are currently analyzing this behavior.
I discovered a specific condition that resulted in inoperable background dragging, as well as the solution. Here are the different states and the behavior:
Condition: Data1, Data2, Data3, and Data4.
Result: Background dragging works.
Modification:
Delete Data3
Condition: Data1, Data2, and Data4 (non-consecutive data numbers)
Result: Background dragging does not work.
Modification:
Delete Data4
Condition: Data1 and Data2.
Result: Background dragging works.
Modification:
Add Data3, Data4, Data5, etc.
Condition: Data1, Data2, Data3, etc.(consecutive data numbers)
Result: Background dragging works.
(P.S. I didn't file a bug report with this solution because the Project Management page isn't responding at the moment)
