Rhino crashes when closing Grasshopper definitions

Hi everyone,

I am writing here because of a weird issue I had in the last days. Due to a severe virus attack I had to reinstall all of my OS and programs on a brand new hard disk. I exploited the chance to finally put up a 64bits OS (Windows 7 64 bits Enterprise).

Before the virus attack my Rhino+GH workflow was totally smooth (I had win 7 Home premium 32bits). Now, since I re-installed Rhinoceros and Grasshopper, every time I close a Grasshopper definition Rhinoceros crashes. I already sent a report to McNeel (file included) but I'm still waiting for the answer.

Any clue on what this might be due to?

Just to give you a complete overview, here's my actual setup:

. Win7 64bits running on HP Pavilion dv 9700 notebook

. RHinoceros 4 sr8

. Grasshopper 0.8.0004 with these extra plug-ins: gEco, Meshedit, Weaverbird, gHowl, Structdraw, SSI for Oasys and SAP2000, Mantis, Firefly

Before the total re-installation I had almost the same software and extra plug-ins except Mantis and SSI for SAP2000. Is it possible that this bug could be due to one of these two (although I doubt it)?

Thank you all in advance for the kind support.

PS: had this isuue been tackled before in another discussion, I apologize (I did a search but could not find anything related to this) and I knidly ask to be pointed in the right direction.

I suspected one of the plug-ins, but I forgot to mention that in the re-installation I switched also from Firefly 1.03 to 1.04, which was giving me an error when using GrasshopperUnloadPlugin in Rhino.

I removed Firefly.gha and everything is running smooth again. I'll try to contact Firefly team to see if it might be something related to the plug-in.

Maybe this can be helpful for others stumbling in my same issue.

Hi Alessio,

I'm looking at the crashdumps you send in and it appears to be due to FireFly. Can you uninstall it and see if the problem goes away?

Hi Alessio,

Thank you for reporting this. It appears there is a bug in the reactivision component which is causing an issue when the document is closed. I will try to fix this and post a new version very soon. Thank you for your patience.

Hi Alessio,

Is there a way for you to send me the file that was crashing the program? I think I may know what's causing the issue, but I'm having difficultly reproducing the problem you mentioned (although I have had this happen in the past too). Do you have a file you could post here (or email me) that consistently causes your program to crash?

Thanks,

Andy

I just wanted to report that I think I have fixed the problem and I will be releasing an update very soon. Sorry for any problems this may have caused.

Hi Andy,

sorry to get back to you only now... I wasn't connected tsince yesterday until this moment. Thank you for the fast fix!

In any case, if it might be of further help, with Firefly 1.004 GH was crashing with any given file I tried to close, not one in particular. I'll download the new release as soon as possible!

Best,

Alessio
