Hello,

I've been checking out Errai and trying out the Store sample
application, and built a simple app myself. This has been to evaluate
the use of Errai in an inhous app. Since that app would mostly be used
by users that have IE7 installed, i did try it in IE7. I encountered
two problems, the first one both in my own app & the sample, and the
second one only in the sample:

1.) The module's icons display correctly in FF, but IE7 instead
displays the whole underlying image generated by GWT from the
ClientBundle that contains all the icons, crammed into the small space
where a single icon should be.

2.) When starting up the sample application in IE7, i get the
following exception:

Am I missing something, or are these some rough edges in the first version?

Thanks,
