[aprssig] aprs.fi embedded and IE9

The reason I ask is this...  Everyone is upgrading that I talk to, Windows 
Live is suggesting everyone update, so those that get the message do.  I 
upgraded my laptop here so I could see what was going on after getting 
somewhere around 100 emails complaining that my website crashed their 


I have an embedded map from aprs.fi and that’s what is causing the problem. 
If there is another way to do it without using javascript as I am currently 
let me know.  Seems to be some size specify error from reading the forums. 
Custom objects get messed up.  Other stuff on my page such as the MNDOT map 
and the weather radar work fine!  But they are size defined by the original 
source.  I tried removing my customized size of 900x600 from the aprs.fi map 
on my page but then the error message changes to minimum size is 200x100 
currently 550x0, and before it was 900x0, it doesn’t like the height setting 
for some reason.

Yes, there are production Web sites that are all in "bug fix" mode right 
having to perform significant re-engineering of their web sites design to 
them work with all the IE-9 "problems".

It might be a good idea to try a different browser than IE-9 right now. 
MS might be able to "fix" these problems, but chances are, that if they fix
them, they'll break all the work these web sites due to work around the 
and then there will be another round of "it's broken".
