fileseekback not working after update to 4.102 - Tera Term Ticket #44061 on OSDN

Hi,

I am using teraterm and macros for years now and with the latest update I did from 4.90 to 4.106, one of the macros stopped working. I could narrow it down to 4.102 being the version where my macro breaks. At one point I am creating a new file, setting a pointer just after creation, then writing a few chars to it and the get back to the pointer and read out that line.

 filecreate writehandle 'version.txt'
 filemarkptr writehandle
 filewrite writehandle 'SomeRandomText'
 filewrite writehandle str

Now the following bit of code stopped working with any version newer than 4.101

 fileseekback writehandle
 filereadln writehandle str
 fileclose writehandle

 fileclose writehandle
 fileopen readhandle 'version.txt' 0
 filereadln readhandle str
 fileclose readhandle
