Textfield on ipad displays only on reload ...

Hi, I have a strange behaviour with the textfield on Ipad :
I have a tour with severals panoramas each with their own xml file, when I load a new pano with "loadpano(pano2.xml, null, MERGE, BLEND(1));" everything works fine except the textfileds that are not displayed, if I reload this pano or another one with a textfield in it then it display allright, it looks that it's only on the first call of the textfield plugin that it doesn't works...
If I call directly the panorama with the textfield it works...

If you want to try go there with your ipad :

http://www.360images.fr/step/mobile.html

clic on this hotspot for example

the textfield isn't displayed :

if you go to another hotspot and come back it will work.

Now clear your cache and go directly to a pano with textfield in it :

http://www.360images.fr/step/mobile.html?xml=innenheim.xml

the textfield is displayed:

I really don't understand the problem, if someone has a clue ?

Thanx !

What's funny is in my case it works perfect on the first load if the panorama with textfield inside is called passing the xml file in the url, but it doesn't work on the first load (it works after) is I call this panorama with the loadpano function...

Bizarre bizarre...
