Hello,
1. Check your graphic card drivers/settings (hardware acceleration on?)
2. Check any 3rd party softwares that can affect normal operation of Windows (accelerators, memory "turbo", antiviruses,
etc, etc)
3. Make sure that you don't have any keyloggers (viruses) trojans running in background - these are very likely to cause slowdowns
not mentioning security issues. There are some trojans that make and send screenshots to hackers. That is going to kill performance.
4. Make sure that nothing has replaced standard Windows Rich Edit controls (riched32.dll riched20.dll)
Best regards,

Yes, i have these spurious copy/pastes too, I had that before but only rarely. Now it is frequent - I figured it was due to my sluggish mouse response.
Something has changed. I am just guessing but it could be the un-do buffer or copy-past buffer that is filing up....but why now, i don't think any of those features have changed for a long time. I must be doing something differently. A chart refresh could cause it (I have extensive ticker trees but they are usually not visible, my layout tab is usually open and on top) however why would that occur during editing?

Herman,
I have the same problem, but haven’t been able to pin it down.
My observations:
Doesn’t seem to happen until I have done a lot of copying and pasting. I can imagine some buffer filling up causing it.
Isn’t related to Indicator maintenance in my case.
When it occurs, it sometimes results in a spurious pasting of some little snippet in the wrong place, which I then have to locate and correct. This can be frustrating!
Doesn’t occur when outside of AB, as in your case.

Subject: [amibroker] Sluggish mouse in Formula editor
The last few days (I never had this before) I often find my mouse unresponsive in the formula editor window. I can click and click until finally (3-4 seconds) my cursor moves and/or I can select text again. It appears that this is due to some AB process using up my computer resources however my task manager shows lots of reserve and i can't figure out what causes it. I am not running any unusual computing intensive processes. My mouse works fine outside of AB.
I am running the IBc with TWS open and my Internet connection is OK. I changed mouse but this makes no difference.
Can this be due to failure to erase formulas when performing Indicator maintenance? I hate to delete formulas... even if they are not to be in actual use.
Would anyone have any idea what can cause this problem?
Thanks,
herman
