I don't know if this is a bug... BUTTON and TEXTBOX objects (instances) in r84 & r85 builds move out of the layout when zoom in or zoom out (ctrl + , ctrl -)in Chrome and Zafari browsers.
here is a link to check it out http://elindiojalapeno.com/bug1/index.html
In Mozilla works fine... They shake, blink, but at last... they stay inside the layout...
If this is not a bug... can someone tell me what am I doing wrong?
