Hi. I would definitely recommend persevering.
All software have bugs of varying degrees, some times caused by the developer sometimes caused by third party components. For example VS is very capable tool, but many of it's own controls (developed by MS them selves) have bugs.
The difference I think here is that MS will take forever (if ever) to correct the bugs even if it is bought to their attention. On the other hand Scirra release regular updates, and if they find the cause of any bugs they will be corrected promptly.
C2 is a very capable tool, and any buggy behaviour is well worth the trouble IMO. <img src="smileys/smiley1.gif" border="0" align="middle" />
