Re: [Alphacocoa-devel] Drag and drop - Alpha 9.1.1

[Greg D. <gre...@in...>]

Just a follow-up - not expecting any action on it, but I wanted to report that this drag and drop failure seems to be very repeatable after Alpha has 
been running for a number of consecutive days.  Restarting Alpha seems to fix it every time.  A sign of the issue is that the cursor remains an I-beam 
instead of changing to the arrow, after the mouse button has been depressed and held.  I have not been able to find a workaround other than restarting 
the application.  My second machine has a new instance of Alpha which was restarted at the same time, as a control.  We'll see if it exhibits this 
behavior, and when.

Interestingly, and even on a fresh restart of Alpha, I will frequently get a file where the cursor remains as an arrow and cannot be changed to the 
I-beam even after clicking multiple locations in the text.  Double-clicking a word or dragging to highlight it and then clicking in the word restores 
the I-beam cursor; clicking outside the selected word or text grouping does not restore the I-beam.  Drag and drop works properly both before and 
after the cursor changes shape.  Notably, switching to another app and then back to Alpha causes the misbehavior to return - this is repeatable. 
Since the block of text becomes (or should be) draggable after selecting and a cursor change is involved in both cases, I have a suspicion that there 
is some kind of correlation here; I have not seen both behaviors at the same time.  If I find other seemingly related issues I will try to document them.

I need to track these items daily under consistent conditions to see if anything occurs (like perhaps the launch of another application) which causes 
the failure to follow.  The last time I did this, it worked for a considerable time and then I forgot to check daily - when of course it began to act 
up.  Sigh.  Closing all windows and creating new ones doesn't fix the issue, so it appears to be something in Alpha's application memory region and 
not in the file's buffer.  I will be a little more thorough and try to pin it down more closely this time.
