reverse flying folder effect when dragging msgs

["Jerry L." <jerryl xemaps com>]

Balsa versions: 2.0.x and 2.2.5

This is one of those things that is much easier to observe than to  
describe, but here goes,,,

After dragging msgs from one folder to another the following often  
happens as a somewhat delayed effect ( a few seconds after the drag is  
over):

For lack of a better term, the "flying folder" icon travels from the  
dragged-to mbox to the dragged-from mbox (ie backwards) for several  
iterations (total possibly due to num of msgs dragged), as if Balsa is  
signalling that the msg drag is being rejected (the msgs, in fact, do  
transfer ok).  This animated icon occurs in the foreground over any  
other cascaded windows, Balsa or not (apologies for the lack of correct  
technical terms).

This can be pretty annoying - does this anomaly, as described, sound  
like a Balsa issue or a Gnome issue?

Any ideas for possible solutions?

Thanks,
Jerry
