I am not able to drag & drop anything into google chrome. For instance, I was able to add gmail attachments using drag & drop until yesterday but today it does not seem to work. Basically when I drag & drop anything onto chrome (not necessarily gmail) I see the 🛇 sign. Version of chrome is "46.0.2490.80 m" and I tried cleaning cahce, deleting temporary files, disabling touch features of chrome, re-installing chrome, uninstalling Avira (browser security), use different mouse, restarting Windows etc. BTW, Drag drop feature of IE and Firefox works just as expected. Actually it was working fine with chrome until yesterday. I tried drag & drop on another PC with very same version of chrome, it just works fine.
I suppose it is not about chrome but about Windows. What may be wrong with my system?
