cannot convert docx to pdf while first process not yet finish....

[myg3nx]

hi, thank for great apps, its very usefull for me and other people out there... i have litle issue that,the program cannot run while first proses not yet finish...
if i open 2 command prompt,

• first command prompt i convert docx (running) , and second command prompt i convert docx (before first command prompt finish), then there is popup window that asking to save file. if you trying convert another docx, while pop up windows is still open, the proses will fail. so u need close popup window, than convert your docx to make it successfull....
• note that i have include switch /noquit and or /readonly didnt resolve the issue... thanks :)
