[OpenLayers-Users] Vector rotation issues with 2.9

[John McGuire]

All,

   I am creating an interface to visualization weather information. 
However, within the past week, we have noticed that when a user zooms in 
and out with wind arrows drawn, the vector is separate from its label, 
and nowhere near its intended direction. I have found that v2.8 does not 
have this issue. Playing with the code, it seems that the rotation in 
v2.9 is the problem, and also exists for the default shape of triangle. 
If anyone would have any further insight to this problem, I would be 
greatly appreciative.

I have included links below to demonstrate the difference.

Thank you all for your help,
