PLEASE SOMEONE CONFIRM THE FOLLOWING BUG
steps to reproduce:
1. create a text file with the following content [ 3gp header as hex (0-9, A-F(not used in this header), space) ]:
---<file content start>---
00 00 00 20 66 74 79 70 33 67 70 35 00 00 00 00
---<file content end>---
2. install ultravnc 1.0.8.4 (latest stable i find today), configure new ms logon groups, enable encryption (SecureVNCPluginARC4.dsm), generate keys
3. go to other computer with vncviewer.exe, SecureVNCPluginARC4.dsm and Viewer_ClientAuth.pkey
4. connect to first computer
5. open the file via remote , select the above text and select copy
6. the viewer instantly closes (tried this several times)
please note: i am not sure whether it`s a viewer problem or a server problem, i might have seen two vnc server icons near the system clock, did not start ultravnc in debug.

bug when copying 3gp header (as hex)
Re: bug when copying 3gp header (as hex)
i just reproduced it again. it`s definitely the server. i`ll start the server in debug, see what happens
Re: bug when copying 3gp header (as hex)
sorry for not hitting edit to add info
so, it seems to be both the client and the server.
vncviewer just crashed. opened visual studio and these are the assemblies:
10005813 pop esi
10005814 pop ebx
10005815 ret
10005816 mov ecx,dword ptr [esi]
10005818 push edi
>>> 10005819 mov edi,dword ptr [ecx+4]
1000581C cmp edi,20h
1000581F jbe 10005838
10005821 push 10035E84h
10005826 push 107h
1000582B push 10035E50h
10005830 call 10004660
error: Unhandled exception at 0x10005819 in vncviewer.exe: 0xC0000005: Access violation reading location 0x00000004.
i am using wx hex editor to copy headers. seems not to work... ?!? some bug there?
still, tried to transfer the 3gp video file and i was unable to transfer it (by file transfer from remote machine to here), i only was able to transfer it after i zipped it.
