Problem after update to Adobe Flash Player 10.3.183.5

Hi all, Please Help ME !!

I have a problem with alignment after Flash Player Update (10.3.183.5).
It was a smooth sliding text field from different side of the screen.
What I used - > a simple text field with negative X parameter (eg. -500) and I tween to 0 (zero) with "onloaded" parameter.
The width of textfield is lower than negative X parameter, so the texfield is out of screen when rendered, and after slides to position.

Everything worked fine till today on both side.
Now it is works if I use align="bottomright". If I try to use with align="bottomleft" it is looks like a vertical text inside.

Here is the small example code:

<krpano version="1.0.8" basedir="%SWFPATH%" logkey="true" showerrors="true"> 
	<preview type="grid(cube,32,32,512,0x000000,0x111111,0x555555);" />


	<!-- ******************** TEXTFIELDS (LEFT - RIGHT) ***************** -->
	<plugin name="right_box" 
		style="box_style"
		html="[br][p]RIGHT ALIGNED TEXTFIELD[/p][br]"
		align="bottomright" 
		x="-500" 
		y="30" 
		onloaded="tween(x,0,2)"/>
	
	<plugin name="left_box" 
		style="box_style" 
		html="[br][p]LEFT ALIGNED TEXTFIELD[/p][br]"
		align="bottomleft" 
		x="-500" 
		y="30" 
		onloaded="tween(x,0,2)"/>
		
	<!-- ******************** STYLE ***************** -->
	<style name="box_style" url="plugins/textfield.swf"
		width="400"
		height="300" 
		autosize="center" 
		css="p{color:#000000; font-family:Arial; font-size:14;text-align:center;}"
		backgroundcolor="0xFFFFFF"
	/>
</krpano>

See the result of above code at http://360emirates.com/panos/textfield_test.php

Please Help Me Find a Solution !!!

Thanks

ps. sorry for my english

Thanks.. but...

The text in the text field is dynamic, so I have to use "autosize".
If I remove the "height" (you are right, no need) the result is same.

I have tried many variations, and if I set the x value to max -280, then works fine on left side too.
It looks, if the negative x value higher than width of textfield.. goes crazy.

So, I don't know... till last flash player update was good .... It seems I have to edit all my old xml files...?? Why ???

If I use this "slide" with y coordinates -> works fine on both side with "autosize".. will good for temporary solution

Thanks Klaus and Sacha.

(...and thanks to "krpanocoder" who posted the bug on "Adobe Bugbase")

I'v seen many other "serious" site has this problem.
I think I'm waiting for a week for new release.. maybe.. I don't want to check and edit my all xml files.
We will update the 360emirates.com in the next month, so if still no workaround, we will use Sacha's "Do It Yourself" method or other solution.

Best Regards

Thanks !

and best regards
